Aerosol dynamics
AEROSOLS: SO4, NO3, NH4, organic carbon (AC),
elemental carbon (EC), mineral dust,
sea salt (NaCl)
Four modes:
1. nuclation (d < 0.02µm)
2. Aitken (0.02 µm < d < 0.1 µm)
3. accumulation (0.1µm < d < 2.5 µm)
4. coarse (2.5 µm < d < 10 µm)
• Calculation of particle mass and number
distributed in four modes, aerosol chemical
composition, as well as, concentrations of PM 2.5
and PM 10 .
